My invention relates to can end flange lining machines and particularly to`an improvement'upon the machine disclosed in Patent No. 1,634,500, granted J`uly. 5., 1927, on application of John 'M. Hothersall, for machine for lining the flanges of can ends.

The principal object of the inventionl is the provision, Vin a machine of this character, of a lining head, or die, having a pump action and being adapted to project a measured charge of lining material forcibly onto the flange in such manner as to` properly apply and distribute it to the flange area to be line Numerous other objects and advanta es of Fig. 2 is an enlarged cross sectional view of the lining die; y Fig. 3 is a partial sectional view thereof,

30kshowing the position ofthe 'arts at the time of contact with the can en. and'just prior tothe charge being squirted onto the flange.;

Fig. 4 is a like view, showing the relation.

plied;and` y f Fig. 5 is a top plan view of the lining ring or die. 1

i On fsaid drawings,pillustr`ating vthe best /lnanner in which I have thus farcontemi plated applying the principlesof m invention, the reference character-11 in icates a table, supportednpon legs 12 and'13, the latter having van inward extension 14, providpower shaft, driven from any suitable source f of power and'a rock shaft 16, `upon which is mounted a bell crank lever 17, clonnected'for actuation of'the lining die in-manner which will presently formed integrally with the table 11, near the the invention will be apparent as it is etter ingbearings for-a shaft 15, which 'may be a .be described. A' tank 18 is:V

center thereof, and the covers are-adapted to be fed along atrack 19 upon said table byl means of a feed bar 21, providedat intervals with` pivoted fingers 22 adapted' to engage behind and propel the covers successively to the lining station and to discharge them from the machine. Said bar is Iformed with teeth 23 on the top thereof at one vend, providing a rack meshing with a pinion 24, carried -upon a shaft 25 adapted to be rotated in opposite directions, in any suitable or preferred manner, proper mechanism for this purpose being shown in the Hothersall pending application above referred to. guideway formed in a top plate 26, said plate being formed to receive. a plurality of `electromagnets' 27 above the liningy station, which. 'magnets serve to hold said covers rmlyin contact with the under side 28 of said plate when at said lining station.

The bell crank,v 17 carries in one arm 29 thereof a cam following roller 31, held in-- contact with a cam 32 on the shaft 15 by means of a spring 33, secured at one end to said arm 2,9 and at the opposite end to a fixed part of the machine. The opposite arm Said bar 21 moves in aN of the bell crank, which is designated by the reference character 34, is pivtall7 connected by means of a link 35 with a rod 36 extendin through a stuffing box 37 and into the tany 18, where it is connected with the lining die which is adapted to be reciprocated thereby, in .manner which will now be described.

The lining die, or head, comprises an outer cylindrical member 38. and an inner member 39, which has a relatively tight friction fit with 3said outer member, saidmembers be.

ing, however, relatively movable in the op- 'l eration of the j device. Said `member 38 1s' formed with web parts 41 at the bottom thereofextending from the-outer-wallfto' a/central y en argement or hub 42, throughl which the rod 36 extends, the' latter being frictionally drical member 38 is `cut away-to rovideta `held therein. The upper edge of the cylnu I pocket 46 forthe Vlining charge, indicated in Fig. 3by`the 'reference character 47, and the inner member is provided with la shoul- *der 48- near the top and awall part 49 thereabove of slightly less diameter than thediameter of a wall part 51 about the pocket 46. Screw rods 52 extend downwardly from a plurality of lugs 53, extending inwardly from the bottom Iof the member 39, and pass through apertures 54 in the web parts 41 of the member 38. On the downward stroke of the head, said rods engage the bottom of the tank 18 and raise -the member 39 to the position shown in Figs. 1 and 2 of the drawings.

lVhen the head is immersed in the semi-liq;

uid lining compound in said tank, the pocket 46 is filled with the lining material, which is carried upwardly thereby, as shown in` Fig. 3, until the wall part 49 of the member 39 comes intojcontact with the flange of the can cover, which is indicated by the reference character 55. Inasmuch as said cover is firmly held in position, as previously described, said member 39 will then be held stationary and the outer ring 38 will be moved relatively thereto to the positionshown in Fig. 4, the lining material being bumped or squirted out between the wall yparts 49 and 51and onto the flange of the, end 55 to provide a liner 56, the size and distribution of which may be controlled in' accordance with the form of the parts 38 and 39.

The amount of relative movement between the parts 38 and 39 can be varied by adjusting the position of the screw rods 52 within their respective lugs 53. Spring pins 45 are positioned between each screw rod 52 and a part of the inner wall of the member 39 adjacent thereto, and in this position are held under tension and bear against thesaid rods 52, preventing accidental turning but permittin adjustment.

-lever 57, pivoted at 58 to an upright 59 extending upwardly from the bottom of the tank 18, 1s provided for the purpose of preventlng operation of the die whenno cover is 1n pos1tion to be lined. Said lever has an upper arm or extension 61, normally held in the path of the ends by means of a coil spring 44 positioned about the pivot point 58, the bottom end of the lever being notched, as indicated at 6 2, and adapted to engage one of the webs 41 of the member 38. In the event that no cover is positioned, said'lever prevents the lifting of the die, in manner which will be apparent, the bell crank 17, in this event, remaining also stationary, the eamroller 31 carried thereby being prevented from following the face ofthe cam 32, the

spring 33 beingvheld extended at such a/time.

If, however, a cover is positioned, it actav upon said lever to cause the same to'disengage said web 41, permitting the lifting of the die and the operation thereof in the manner hereinbefore explained. The reference character 61 indicates a vent pipe, of 4which there may be one or more, in the tank.

It is thought that the invention andmany of its attendant advantages will be understood from' the foregoing description, and it and apply the same to the flange of a can end, said head comprising parts relatively movable on the up stroke of the head to squirt the lining material onto the end flange.
